HEINRICH FLEISGHHAUER, OF BERLIN, GERMANY.

HORSE-DETACHER.

SPECIFICATION forming part of Letters Patent No. 253,690, datedFebruary 14,1882.

Application filed October 1, 1881. (No model.)

To all whom it may concern Be it known that I, HEINRICH FLEISCH- HAUER, of Berlin, Germany, have invented a new and useful Improvement in Apparatus for Instantaneously Loosening Traces, of which the following is a specification.

The object of my invention is to facilitate attaching and detaching the traces of animals of draftto or from the whiflletree'or draft-bar.

The invention consists in a spring-actuated sliding pintle or bolt for holding the traces,

' which bolt can be withdrawn from the aperof the apertured end of the trace.

ture in the trace by turning a collar with a spiral or beveled track, which collar can be rotated from the drivers seat, thus permit-ting the animals to be released instantaneously in case of accident, as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part ot' this specification, in which similar letters of reference indicate corresponding parts in all the iigures.

Figure l is a longitudinal elevation of one of the trace-holders of my improved device for releasing traces. Fig. 2 is a. cross-sectional elevation of the same, showing the pintle or bolt raised. Fig. 3 is a cross-sectional elevation of the same, showing the pintle or holt lowered. Fig. 4 is a sectional plan view of the same on the line x, Fig. 1. Fig. 5 is a detail plan view of the same. Fig. 6 is a side elevation of the spiral cam for raising the pintle or bolt. Fig. 7 is a sectional plan view of the pintle or bolt on the line y y, Fig. 2. Fig. S is a plan View of a whifdetree provided with a trace-holder at each end, the two trace-holdersA being connected. Fig. 9 is a perspective view Fig. l() is a plan view of' a whifletree for a team, provided with four trace-holders connected with each other. Fig. 1l is a plan view ofthe moditication of the trace-holder, showing the pintle or bolt passed through the trace. Fig. 12 is a plan view ofthe same, showing the pintle or bolt withdrawn. Fig. 13 is a cross-sectional elevation of the same, showing the positions of the several parts when the pintle or bolt is passed through the trace. Fig. 14. is a cross sectional elevation of the same, showing the positions of the several parts when the pintle or bolt is withdrawn. Fig. 15 is a plan View of a whiftletree provided with trace-holders of the modified construction. f

A pintle or bolt, A, slides in a casing, B. provided with a socket, C, for the trace D, and attached to a whietree, E, in such a manner that the opening ofthe socket O will be at the front edge ofthe whiffletree. The bolt or pintle A must be of such length that it can cross the socket C. The pintle or bolt A is provided with a removable head, B', which rests on the top A of the casing B when the pintle or bolt A is in its lowest position. A spiral spring,

F, surrounds the bolt A, and rests against the l under side of the top A of the casing B and against an annular ridge, G, of the pin or bolt,

this spring F having the tendency to press the I shoulder or track, H, of a small cylinder or collar, H, pivoted on an extension or projection of the casing B, and provided with-an arm or lever, J, extending backward from the whiftle tree. A latch-lever, K, provided with a handle, L, and with a vertical stud, M, is pivoted on the top A of the casing B. There is one casing B at each end of a singletree, and the two arms or levers J are connected by a rod, N, and one of the arms J is provided with an eX- tension, N. lf two animals draw on the same whiflletree, the whiflletree mustbe provided with four casings B, as shown in Fig. 10. Each trace must have an aperture, O, in its rear end large enough to admit the pintle or bolt A.

lf the device described above is used, the end of the trace must be in a horizontal position. The construction of the details of the Vdevice may be modified without deviating from the main principle of theinvention, as will now be described, reference being had to Figs. 1l to l5, inclusive. The pintle or bolt A2 is arranged to slide horizontallyin a easing, P, and has its the same is placed vertically or edgewise, as shown. A collar, It, with a spiral or beveled edge, is rigidly mounted on the bolt, and a sleeve, R', also provided with a beveled or spiral edge, is loosely mounted on the bolt A2, and is provided with an arm, S, which is held by a bolt, S', to a longitudinally slotted connecting-bar, T, the bolt S' passing through the slot T' of the barT, which is pivoted to an arm, U, of a rod, V, journaled in the casings I? and provided with a handle-lever, W. A spring, Y, attached to the casing I?, presses the bolt A2 in the direction toward the trace-socket Q,- that is, the spring Y keeps the bolt closed.

In both the devices described the bolt or pintle is operated by means of a collaror sleeve 'with a spiral or beveled edge or ridge.

The operation is as follows: To fasten the traces in the trace-holders the arm N is moved in the direction of the arrow a', whereby the cylinders H will be turned or rotated, and will thereby raise the studs G' resting on the spiral or beveled tracks H' of these cylinders H. Thereby the bolts or pintles A will be raised and the springs F compressed, as shown in Fig. 2. The latch K is then turned in the direction ofthe arrow b,s0 that the stud M will pass under the head B'. The bolt or pintle A is thus held in a raised position, thereby permitting the traceD to be inserted in the socket G. Then the latch K is moved in the inverse direction ofthe arrow b', thereby releasing the bolt A, which is forced downward through the aperture Ooi' the trace by the spring F. Thus, if the animals run away or fall,or if at any time or for any reason they are to be released suddenly, all that is necessaryis to push the lever N' in the direction ofthe arrow a'. The bolts A will be raised, the traces D will be released, and can be drawn out of the sockets C by the animals.

The operation of the modifications shown in Figs. l1 to l5, inclusive, is similar. To draw the bolt A2 out of the trace-socketsQ the hand1e-lever XV is pressed downward, as indicated by the arrow c', whereby the lever or arm S will be broughtinto theposition shown in Fig. 14. The sleeve It' is partially rotated, and the collar R and the bolt A2 are moved in the direction of the arrow d'. Then the handle-lever YV is raised in the inverse direction of the ar- A2, which is pressed in the inverse direction of the arrow d' by the spring Y, thereby passing through the aperture in the trace. Thus all the traces will be released simultaneously in case of accident by simply pressing the handle-lever W downward.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In adevice for looseningthe traces of animals of draft, the combination, with a sliding bolt, of a rotating collar with a spiral edge or ridge for operating the bolt, and of a spring pressing on the bolt, substantially as herein shown and described, and for the purpose set forth.

2. Ina device for loosening the traces of animals of draft, the combination, with the casing B, ot' the sliding bolt A, the annular ridge G, the projection G', and the rotating collar H, provided with a spiral ridge or shoulder, H', substantially as herein shown and described, and for the purpose set forth.

3. In a device-for loosening the traces of animals, the combination, with the casing B, of the sliding bolt A, the annular ridge G, the projection G', the spiral spring F, and the rotating collar H, provided with a spiral ridge or shoulder, H', substantially as herein shown and described, and for the purpose set forth.

4. In a device for looseiiing the traces of animals of draft, the combination, with the casing B, ofthe sliding bolt A, the an nnlar ridge G, the projection G', the spring F, the collar H, having a spiral ridge, H', and the lever J, projecting from this collar H, substantially as herein shown and described, and for the purpose set forth.
